Abstract
This paper describes a magnetometer with a miniature transducer which can be scanned automatically. The active area of the transducer is 0.64×0.76 mm and its drive circuit is constructed from wire plated with a magnetic coating. The magnetometer is capable of detecting static magnetic fields as low as 0.02 Oe and can measure magnetic fields as close as 0.08−0.10 mm from a relatively flat surface since the transducer is flat and rugged. The magnetometer is simple to operate and has a fast response. The instrument has been applied to the measurements of magnetic fields arising from remanent magnetization in experimental plated-wire memory planes and regions of magnetic activity in geological rock specimens.
